Checking and Testing

• To see if cables and wires are working properly, check with a multimeter. If it reads zero, it is in good condition while infinite means broken.
• In switches/buttons, zero at 1st attempt and infinity in 2nd attempt means it is in good condition.
• In fuses, if the meter reading is zero, then it is in good condition.
• To test capacitors, set the meter to read in the high ohms range. The meter should start at zero then slowly move toward infinity.
• Diode and LED - Must have a voltage drop ranging 0.5 to 0.8 volts, or 0.2 to 0.3 volts. When a good diode is reverse-biased, it shows OL.
• In testing resistors, if the reading is the value and tolerance range of the resistor, it is good.
• Records Management - the field of management responsible for the efficient and systematic control of the creation, receipt, maintenance, use and disposition of records.
• Metadata provides information about other data, an information about a certain item's content.
• Records survey is the gathering of basic information about records regarding their quantity, physical form and type, location, physical condition.
• A physical survey is the most reliable form of survey used when it is

  important to obtain detailed, accurate information as to the records held by the area.
• A survey by questionnaire is a quick method of containing a wide area.
